Technical Properties & 99% Purity Quality Control of Propyl Gallate CAS 121-79-9 E310 Antioxidant

Technical Research Brief

As a professional food-grade antioxidant coded E310,Propyl Gallate CAS 121-79-9 features unique molecular structure and targeted antioxidation performance. This article focuses on its intrinsic chemical mechanism, special physicochemical characteristics and high-purity quality control standards, providing professional technical reference for raw material screening and laboratory research.

Propyl Gallate (CAS 121-79-9) is a synthetic phenolic antioxidant with a specific trihydroxy benzene ring molecular structure. Different from broad-spectrum natural antioxidants, its structural characteristics enable it to specifically capture free radicals generated during lipid peroxidation, effectively delaying the oxidative rancidity of grease substances. This targeted molecular reaction mechanism is the core reason why E310 Propyl Gallate becomes a dedicated antioxidant for edible oils and fatty systems.

I. Unique Physicochemical Characteristics and Chemical Traits

99% min high-purity Propyl Gallate powder presents excellent oil solubility and outstanding thermal stability, adapting to high-temperature processing environments of fatty food production. Meanwhile, it has inherent chemical sensitivity: prone to photolysis under long-term light exposure, hygroscopic in humid environment, and easy to produce discoloration reaction when contacting iron and copper metal ions. These unique traits are key technical indicators that distinguish Propyl Gallate from ordinary antioxidants and are critical factors affecting raw material storage and formula application.

II. 99% High Purity Standard and Impurity Control Logic

Low-purity Propyl Gallate contains residual impurities and excessive moisture, which will not only weaken the antioxidant effect, but also induce secondary oxidation of grease and abnormal color deviation of finished products. Our 99% minimum purity standard strictly controls harmful impurities, moisture content and chromaticity indicators. Through standardized purification technology, the batch stability of molecular activity and powder appearance is guaranteed, avoiding quality fluctuations in downstream lipid systems.

III. Professional Storage and Batch Technical Support

Based on the photosensitive and hygroscopic characteristics of Propyl Gallate CAS 121-79-9, we implement standardized sealed, light-proof and dry storage specifications. Each batch is equipped with complete COA test reports, covering purity, melting range, moisture, impurity content and other core indicators. Professional storage and transportation guidance is provided to help users avoid raw material iNACtivation and application failure caused by improper operation.
